Definitions

  • Control- and operatingsystem in particular for a hydraulic actuator of a folding roof of a vehicle.
  • the invention relates to a control and operating system according to the preamble of claim 1.
  • the known system provides for a
  • control unit should be wo.--TM,, . . .
  • the object of the present invention is therefore to propose measures which make it possible in a simple manner
  • the electric control unit is designed in such a way that in the condition of the control element for holding the foldable roof unit in an intermediate position said control unit supplies a signal to the electromagnetic control valve during a first period
  • control valve 30 by means of which the control valve is constantly energized during this first period, and in a subseguent, second period supplies a signal to the electromagnetic control valve, by means of which the control valve is intermittently energized and not energized such that the
  • 35 part of the foldable roof unit which is movable by the hydraulic piston-cylinder unit executes a downward movement under the influence of gravity in a stepwise manner during the second period.
  • the measure according to the invention can be achieved by adapting the program stored in the microprocessor of the control unit 15.
  • the hydraulic set-up need not undergo any change in order to realize the inventive idea.
  • the first period in which the control valve concerned remains energized continuously, can be selected for so long that the holding function need not be broken off for a duration which is considered normal in practice for said holding function.
  • the period of time during which the control valve concerned is not energized in each case can be selected in such a way that a stepwise, and in particular slow downward movement of the corresponding part of the foldable roof unit occurs. This is safe for the passengers and any bystanders present. In particular, it is found that, due to the inertia of the parts of the roof, it is hardly noticeable that the downward movement is taking place in a stepwise manner.
  • Another advantage of the invention is that the battery of the vehicle, which supplies the energy for keeping the control valve energized, can be saved, since the holding function can now be completed safely.
  • double-acting hydraulic cylinder 1 serves to open and close cover 2 of a foldable roof unit (not shown) of a motor car.
  • a cover 2 is generally used for covering the opened-up roof, which is accommodated in a compartment at the back of the car.
  • Piston 3 of the cylinder 1 forms two working chambers 4 and 5 with variable volume in the cylinder 1.
  • supplying hydraulic fluid to the working chamber 4 leads to the cover 2 moving upwards.
  • the working chamber 4 is connected by way of a line 6 to a pump 7.
  • the pump 7 can suck in hydraulic fluid by way of line 8 from reservoir 9 and supply it to the working chamber 4.
  • the line 6 contains a non-return valve 10, which prevents flow from the working chamber 4 to the pump 7, but allows it to pass in the opposite direction.
  • An electro- magnetically operated 3/2 valve 12 with spring return mechanism is accommodated in the line 6 between the non ⁇ return valve 10 and the connection to the working chamber 4.
  • the valve 12 is driven by an electric control unit 14, which is connected by way of a signal line 15 to the valve 12.
  • the control unit 14 comprises a control button 16, which can be operated by the driver of the motor car.
  • the button 16 has three positions I, II and III. So long as the driver holds the button 16 in position I, the control unit 14 makes the foldable roof of the car open, and in position III makes it close. When the button 16 is released, it assumes position II. If the button is in position II and the foldable roof is not in the fully opened or the fully closed position, the control unit 14 produces a "holding function". This means that, for example, when the cover 2 is in the position shown in the drawing, hydraulic fluid is prevented from flowing out of the working chamber 4 into the reservoir 9 and the cover 2 is prevented from folding down unimpeded under the influence of its own weight.
  • control unit 14 is designed in such a way that while the holding function is switched on for a first period, which can be for a number of minutes in practice, the valve 12 is kept energized.
  • the non-return valve 10 prevents hydraulic fluid from flowing out of the working chamber 4, with the result that the cover is held up.
  • the non-return function can be integrated in the valve 12, so that it is possible to dispense with the non-return valve 10 placed separately in the line 6.
  • the electromagnetically operated valves used in this field do not permit unlimited energization, because overheating can then occur.
  • the present invention therefore ensures that before any overheating can occur, the continuous energization during the first period is followed by an intermittent energization for a second period.
  • the signal delivered by the control unit 14 by way of the line 15 to the valve 12 is such that the valve 12 is alternately energized and not energized.
  • the result of this is that during each phase of the valve 12 not being energized hydraulic fluid can flow out of the working chamber 4 into the reservoir 9.
  • the cover 2 will consequently move downwards in a stepwise manner under the influence of its own weight.
  • the downward movement can be given any desired course.
  • the movement can be slow at first and can speed up slightly on approaching the end position. Determining the desired movement course is very simple if the control unit comprises a microprocessor, because all that is then necessary is the input of a suitable program.
  • the duration of the second period is preferably chosen to be so long that the cover can reach its end position from each initial position.

Abstract

Système de commande et d'actionnement comportant un vérin hydraulique (1) servant à déplacer une charge (2). Le piston (3) délimite une chambre de travail (4) qui, alimentée en huile, déplace la charge reliée au piston en s'opposant à la pesanteur. La chambre de travail (4) est reliée à une pompe (7) par l'intermédiaire d'une canalisation (6) dans laquelle sont installés un clapet anti-retour (10) et une vanne de commande électromagnétique (12). A l'état non actionné, la chambre de travail (4) est reliée à un réservoir (9) et, à l'état actionné, elle est reliée à la pompe (7). L'unité de commande est conçue de sorte que, dans la position dite de 'blocage' du bouton de commande, la vanne de commande (12) est actionnée en continu pendant une première période, puis, pendant une seconde période ultérieure, elle n'est actionnée que de manière intermittente. Par conséquent, la charge s'abaisse par paliers au cours de la seconde période.
